title: Assessment of dietary intake and nutritional status (MNA) in Polish free-living elderly people from rural environments.
abstract: The proportion of elderly people in the global population is rapidly increasing. Their nutritional status indicates many deficiencies that are risky to health. The aim of this paper was to assess the nutrition and nutritional status in elderly individuals above 60 years old living in their family houses in rural areas. Dietary intake and nutritional status were measured in 174 elderly women and 64 men living in the rural areas of Oleśnica (near Wrocław, SW Poland). Energy intake, consumption of nutrients, selected anthropometric and biochemical indicators, were measured in two groups: one at risk of malnutrition and one with adequate nutrition. Using the mini nutritional assessment (MNA) questionnaire, 238 persons over 60 years of age were qualified according to their nutritional status. Anthropometric and biochemical parameters were measured. The group of women at risk of malnutrition (n=30) showed a statistically significantly lower energy intake in their diet (1,127 kcal) compared to women with adequate nutrition (1,351 kcal). The entire group of examined individuals showed a too low consumption of fiber, calcium, vitamins C and D, and folates. Most of the examined women had a too high body mass index (BMI) (on average 28.8), waist circumference was 96.3 cm, and the triceps skinfold (TSF) was 25.2mm thick. Women at a risk of malnutrition had statistically significantly lower lipid parameters than those with adequate nutrition (respectively: TC 191.1 vs. 219.1m/dl, p<0.001, LDL-cholesterol 107.1 vs. 125.1m/dl, p<0.008, TG 129 vs. 143 mg/dl). Men with a risk of malnutrition had a statistically significantly lower BMI (26.0 vs. 28.7, p<0.04), and also lower waist and arm perimeters compared to men with correct nutrition. According to the Charlson comorbidity index (CCI), 8.2% of person with adequate nutrition had poor prognostic indicator for overall survival. All the examined individuals showed many significant nutritional deficiencies. The group with nutritional risk had more pronounced nutritional deficiencies. Despite a too low energy value of foods among individuals with correct nutrition, their anthropometric parameters paradoxically showed the presence of excessive fatty tissue. The most frequent diseases existed in examined group were coronary artery disease and congestive heart failure.
